it PATENT FFIGEQ SPECIFICATION forming part of Letters'latent No. 656,483, dated August 21, 1 900.

Application filed February 25, 1898:. I Serial No. 671,578. (No model-l To all whom it may concern? I Be it known thatI, WALTER SooTr', a citi zen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvementsin Motor-Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Myinvention has for itsobject theimprove ment of the driving, driven, or running and steering gear of any motor-vehicle. The driving-gear comprises theengine, receiving motion from any desirable motive power, a central rearward-projectin g driving-shaft under neath the body of the carriage with different stylesof connection between the crank-shaft and said driving-shaft and driving-shaft and the rear axle. The driven or running gear comprises the rear wheels of the vehicle and the different methods of connecting these with the driving-shaft, and the steering-gear comprises all the elements that appertain to guiding the vehicle in any desired direction, said steering-gear located in the front part ofthe vehicle, so as to be within easy reach of the motorman.

of the crank-shaft, including the driven or running gear, my invention will undergo no change, whatever motive power may be applied. The said motive power, which can be applied to the ordinary cylinder piston or pis From the poiritwhere the piston rod or rods act upon the crank orcranks' erence indicate corresponding parts in the .j'different views, and in which-A 1 Figure 1 shows a side view of a vehicle; 1 Fig. 2, a top view of Fig.1; Fig. 3, a broken detailview of an other connection between the crank-shaft and driving-shaft and another View of the "connection shown in Figs. 5 and 7 between the driving-shaft and the rear axle Fig. 4, an end View of a Worm and worm-gear connection between the rear axle and the driv ing-sha'ft; Figs. 5 and 6, modifications of the same connection; Fig. 7 a top view of Fig. 5; Fig. 8, a detail view of the spring and lover attached to the pivotedgearing connection shown in Fig. 1 between the steering-gear and the front wheels; Fig. 9, a front end View of the truck of a vehicle, showing a modification of the steering-gear shown in Figs. 1 and 2, andFig. 10 a detail viewof the spring-andlever attachment shown in Fig. 8.

, The gearing revolving the wheels and the steering apparatus are attached to the carriage in the following manner: The vehicle body proper, I, has a front platform J and in the rear a pair of arms J and J This platform has the appliances for generating the motive power mounted on it, besides the manip-.

sisting of a standa'rdK, through which runs a rod K, having at the upper end. a mitergear K meshing with a companion gear K supported in a bracket,which is part of standard K, to which is finally attached a handwheel K At the nether end of rod K is similarlyattached one of a pair of miter-gears, K the other, K, being secured firmly to a Worm KQsupported in a pair of arms that form part of bracket K supporting the front of the vehicle at three points K K and K. The worm KT gears into a worm-wheel K the gear out only one. semicircular segment thereof. The worm-wheel is. part of a circular plate or disk having four arms K suitably mounted on the horizontal and lateral extending arms K and K, resting on and secured to their respective carriage-springs K and K, which again rest on and are suitably at nectedas follows: Suitably supported in an engine D is a crank-shaft D having cranks D and D This is, by the universal coupling D", connected with the driving-shaft D .A modification of this connection between the crank-shaft and the driving-shaft is shown in Fig. 3, where the end of shaft D is supported in the engine-shell and connected with the. crank-shaft by spur-gears D 9 and D Said shaft D is supported in the engine-shell D in hubs D and D and the extension thereof or the driving-shaft D is supported in the other end in the casing L, which incloses the part oft-he running or driven gearing attached to the rear wheels of the vehicle. The said extension-shaft D has securedto it'a worm H meshing with a worm-Wheel in a fitting mechanical manner.

Z, which is secured to the rear axle M journaled in the customary boxes, said boxes havinginterposed-between them and the rear supporting-arms J and J of the carriage springs M and M all of which journal-boxes, springs, and rear carriage-arms are secured together Secured firmly to the shaft M is one of the rear wheels M while the other rear wheel M is formed with a sleeve M that fits around the shaft M M having the fourth cog-wheel N of a compensating gear, consisting of the two pinions N and N pivoted in the hubs N and N on'the cog-wheel N, which is firmly secured to the shaft M The worm-wheel'Z is fittingly secured to the shaft M and, as will be seen in Fig. 2, lies around the compensating gear and can either be attached directly to the shaft M orbe cast in one with the part of the compensating gear formed by N, N

- vehicle from the point where the power is applied, it will thus be seen that the motive power will transmit motion to the cranks D and D which will finally transmit power to the driving-gearing.

The steering apparatus is operated, as follows: The motorman from his seat S manipulates the hand-wheel K, which, having firmly attached to it the miter-gear K meshing with a companion gear K secured at one end of the rod K at the top of the standard K, will thus transfer motion to the miter-gear K attached to the other end of the rod K. Gearing into this is a companion gear K secured firmlyto a pin having the worm K attached to it, said pin supported in bracket-arms forming part of the disk K which is an immovable part with the under part of the carriage, formed by the carriage-arms K and K, springs, boxes K and K containing the axle K and wheels revolving at the end of said axle. A disk K with a segment of a -worm-wheel attached, gears into the worm K supported, as aforesaid, in a bracket formingpart of the disk. K so'that it will be apparent that a right or left motion of ninety degrees can be given to the axle having wheels revolving thereon, which was the object I had in View. I 1 V I In Fig. 81 have illustrated a modification of theworm-gear K and its connection with the disk K as follows: The worm-gear K is constructed as running loose around the disk F to the extent of the length of the slots F and F out in said disk, which disk rests on top of the disk K and has connection therewith by means of the two bolts F and F fastened in K and protruding through the slots F and F Secured on disk F are, further, a Shell F (seeFig..10,) having an open and closed end, acoiled spring F lying inside of it, a set-screw F attached in the closed end and having a plate F at the end inclosed in the shell resting'against one end of. the spring F The other end of the spring F bears against a lug F cast on or otherwise attached to worm-gear K It will now .be seen that the above-described construction is an elastic take-up motion for any sudden jerks in the gearing caused by the wheels meeting obstructions which might occasion breaks. Another take-up motion can be placed on the opposite side to take up the opposite motion. The steering motion, being transferred through the worm K to the worm-gear K is transmitted to the disk K by lug F acting on the spring F located in the shell E, which shell forms part of the circular disk F lying inside of the worm-gear K which disk is attached to the underneath-lying disk K by the bolts F and F attached to disk K moving in the slots F and F in disk F thus causing an easy elastic movement between the steering-gear and the front wheels.

Referring to the modifications for connecting the wheel-axle M with the driving-shaft D, the illustration in Fig. a'shows thedriving-shaft having"the worm H secured to it, said worm supported in the arms Y and Y of a bush Y, which bush itself runs loose on the axle M and to prevent the friction from carrying it around with the said axle it is furnished with a pin Y and is vertically adjustable up and down in support Y", attached to the under side of the truck-body, the worm H gearing into worm-wheel Z, thus revolving M In Figs. 3, 5, and 7 the motion from the driving-shaft D is transmitted by means of the spur-gear 0, attached thereto, meshing with its pinion 0, said pinion attached to a pin carrying also the worm H supported in the arms 0 and O and forming part of a bush lying, as in the instance of bush Y, around the axle M and moving loose on the same, bush Y also having a pin Y secured in a support Y attached to the truck-body, and finally the worm H gears into the worm-wheel Z on the driven axle M worm for each wheel.

'In Fig. 6 the driving-shaft D has a bevelgear P attached to it, meshing with a bevelpinion P, secured to a pin P carrying the worm H said pin supported in the arms 0 and 0 forming part of the bush Y, loosely secured to the axle M having a pin Y steadying it in a support Y, which support is attached to the truck-body asin the former instances, the connection being closed byworm H gearing into worm-wheel Z, attached to shaft M A modification of the steering apparatus shown in Fig. 1 is illustrated in Fig. 9. The wheels Qand Q are in this instance swiveled at the pivots Q. Looking at the construction of one of these wheels, one description sufficing for both, it will be seen that the pivot Q has at its lower extremity a worm-wheel Q firmly secured. The pivot Q itself is either a substantial partof or firmly secured to the axle-pin Q", the wheel Q, its axle-pin Q the pivot Q, and the worm-wheel Q consequently forming a unitary element. The said pin Q is movable in two arms Q and Q forming part of the axle K. The axle K having boxes R and R inclosing springs R and R supports the front body of the truck. Gearing into the worm-wheel Q is a worm K and, speaking about both worm-wheels, 'a Said worms K are mounted on a shaft T, which shaft is supported in arms V and V forming part of the axle K Said shaft T has, furthermore, one of a pair of miter-gears K attached to it, the other miter-gear K being secured to the end of a perpendicular rod K, which passes through and is supported at the top by a standard K, which rod K has a hand-wheel secured to its upper end for manipulation by the motorman. It will consequently readily be seen that when the motorman turns the hand-wheel either to the right or left side the rod K, having the miter-gear K firmly secured thereto, will actuate the companion miter-gear K secured to the shaft T, and shaft T, having the Worms K attached, gearing into their respective worm-wheels, forming part of a unitary element with the wheels Q and Q, will turn these in either a right or left hand direction. It may be added that the spring device or take-up motion (illustrated in Figs. 8 and 10 and described before) can be applied in the same manner to the Worm-gears described in this construction, in which case one spring may be furnished for each segment, and it will be readily understood that it is not necessary for the hollow axle M to be constructed hollow, but that it can be constructed like M and the ends terminating adjacent to each other and supported by suitable bearings. Further, the worm-wheel Z could rotate on a separate bearing other than the axle.

As the operative motion of each division has been explained and the cooperative union between the above-described elements has unavoidably formed part of the description, no rsum of the same would seem necessary; but

WVhat I claim as my invention, and desire to secure protection for by Letters Patent of the United States, is.-
